Hurricane Agnes

Bottomed out at 43 this morning and made it up to 51 for a high. It's currently a pea soup-thick foggy 49 (vis. < 1/10th of a mile) with dp 48.

The couple nights that stayed above freezing pretty much knocked everything on the grass and streets completely out. The giant plowed mounds in the supermarket lots are still there though. Made it up to 44 for a high yesterday, bottomed out at 43 this morning, and ended up at 53 for a high today. The fog where I am was much greater yesterday than today although where my sis is in Wyndmoor, they had much more today (more open areas still had snow cover there). Was expecting more rain by now (had 0.03" yesterday and 0.21" today so far), but will see what might bubble up overnight. Currently a misty 51 with dp 51.

Ended up hitting 36 for a high today so had lots of slushy shoveled/plowed mounds that will freeze solid tonight. Currently 30 with dp 20.

12z Canadian has the High oozing down just after the precipitation has mostly moved OTS.

Looks like the suggestion was that a Canadian High was going to ooze down over NE and chill things as the Low passes off the coast. Nailing that this far out (for GFS) might be dodgy though.

Wanted to wait until after sunrise this morning to confirm but my low this morning was 20. And although the winds relaxed after about 6 pm last night, they never went calm, and there were puffs of a breeze on and off all night, so the ideal radiational cooling wasn't in effect. Currently mostly sunny and 23 with dp 16.

Bottomed out at 20 this morning and made it up to just under freezing with a high of 31. The wind was blowing a lot of the powder off the roofs in the area in any case. I also noticed that some time after noon yesterday, my station's anemometer and vane managed to free themselves from their frozen encasement and were moving again. Currently clear and 29 with dp 14 and I expect the radiational cooling will be in full effect tonight.

OMG it's been a LONG time since we've seen the epic snow pile at your spot! As powdery stuff, six on one side says it would go quickly and a dozen on the other says if there is some rain in there with melting and refreezing, the potential for glacier creation would be there to help build a solid foundation. So far today (and probably the final) my "high" for the day was 23 at midnight as I got no higher than 22 during the daytime hours. It's currently partly sunny but with a high cloud deck moving in, and 22 with dp 9.

Bottomed out at 17 this morning and did the initial car clearing. Thankfully that was some powdery stuff (compared to the powder from the earlier storm that had a 1/4" crust of ice on it ), so was able to clear most of it pretty quickly. The winds have picked up so the snow is now blowing around. Currently a sunny but chilly 21 with dp 10.

I did a double-check earlier this morning to see if any amounts changed after my last 4.25" measurement around 5 pm yesterday, and it didn't, so am going with that. Just came in from removing the snow from the car and thankfully it is some really powdery stuff. I saw the winds had started to pick up so figured better get it done now since it's also blowing around, and that would aid getting leftovers off the roof (have a big SUV). Currently breezy and sunny, with lots of cumulus, and 21, with dp an arctic 10.

10 pm Jan. 19, 2024 PNS - PHL reported 4.6" (ASOS). Looks like far South Jersey and Northern Delaware got under the heavier bands. I may go do one more reading as I noticed some cars that had been cleared after people had returned home from work last night, looked to have been dusted again when I checked this morning.

Did a ~5 pm measurement and that back-build after I did the 3 pm one, did net me another 1/4", so for today (at this point), I am up to 4.25". Am down to snizzle now with temp 27 and dp 25. Mt. Holly's 3:40 AFD for the city mentioned possible stuff rotating around through the rest of the evening so who knows? Some who are north of the current heaviest bands might cash in on some bonus flakes.

Down to SN-- which is a bit more than flurries or snizzle but is probably looking sparse due to the fine pixie dust flakes. Not sure how much that would have contributed to my 4" since the last check, but it looks like the swath of precip on radar is pulling away to the SE. Will probably do one more measurement before it gets too dark (sun is setting just after 5 pm now). Currently 27 with dp 26 and a little bit of fog off in the distance.

Am getting a bit of a back-build band that upped the intensity a bit intermittently.

My 3 pm measurement was 4" on the nose. So far the winds have been non-existent, so I haven't seen any snow blowing around. Am down to SN- with fine flakes, a temp of 28 and dp 26.

You can see that one low rolling OTS!

Last HPC surface map (from about an hour ago I believe) -

12:15 pm measurement was 3.25" and the flakes are back to the smaller/finer type and still going at a steady SN rate. Temp is now 28 with dp 26.

Must be some kind of warm layer up in the atmosphere as I'm starting to get some pancakes mixed in with regular flakes (the fine stuff has been reduced to a min, although the pancakes will help increase the snow pack faster). Temp is still 27 with dp now 26 with some fog. ETA - running an animation of the radar suggests a band is back-building over I-95 so what might have appeared to be a "back edge" hasn't moved that much.

Just measured and have 1.75" on the board with moderate snow. Getting bigger flakes mixing in now and am under a stronger blob. Temp is 27 with dp 25.

I am at my low for the day so far (26) where I had a high of 30 (so far) just after midnight. Currently light snow and 26 with dp 24.

Now have SN with fine powdery flakes quietly building up a bed of frozen precipitation. Eyeballing about 1/2" so far IMBY, with temp at 26 and dp 24. My station anemometer and vane are frozen over (the station is about 7.5ft above the ground so would probably need a ladder to carefully knock off the chunk of frozen slushy snow sitting on top of it, without breaking the wind instruments).

It's showtime! At some point before 6:30 am here, I looked out and a burst of snow apparently came through and added a dusting to cold/untreated surfaces. Currently SN- and 26 with dp 23.

Yeah but the HRRR updates every hour so with each run, you have a new chance at winning!

Currently bopping between 29 & 30 with dp 20. I did finally clear my board this afternoon, so we wait. If the winds appear as progged, it might be tricky to get a good measurement assuming snow ratios will allow it to blow around more.
